Abstract

A tamper evident assembly for retaining a plunger and/or piston within a barrel of a syringe comprises an elongated tether disposed in an operative attachment and position on the syringe. When operatively attached, a connector assembly adjustably and fixedly interconnects the tether to an exterior of the barrel of the syringe concurrently to one end of the tether, and with a retaining member associated with the opposite end of the tether disposed in a removal restrictive relation to the plunger and/or piston, on the interior of the barrel. Movable adjustment of the tether relative to the connector assembly defines a retaining segment which can be disposed into a fixed length and taut orientation, between the ends of the tether, to further define the operative attachment or position.
